tyler1338195y@alexbrooklyn my php docker container using an .env file wont connect to my mongodb in another environment. Im thinking cause its binded to 0.0.0.0 i should bind it to 127.0.0.1 in the docker compose. Any suggestions?
-
@tyler1338 First thing I'd do is throw out the .env file and switch to environment variables
But you both run them in docker-compose right? Are they both connected in a network? Does the mongodb have an open port with expose ?
What address do you use in the php container to connect to the mongodb container? -
tyler1338195y@alexbrooklyn i can connect to the container using localhost from my machine but when it comes to the other container connecting it doesnt work.
-
@tyler1338 Yep, that makes perfect sense.
You see, a container has its own network, so using 'localhost' inside a container will point to the same container, so itself.
Docker and docker-compoes have a great way of connecting containers and that is using the service name of the container you want to connect to.
For example:
---------------------------
networks:
database: ~
services:
mongodb:
image: ...
network:
- database
[...]
php:
image ...
network:
- database
[...]
-----------------------
Then you can replace 'localhost' in your php container with 'mongodb'.
Also, I really advice to delete the .env file, it makes your container inflexible, opposed to environment variables that allow you to configure stuff from the outside.
